Storage Technology
HDD (hard disk drive)
- large (10TB), cheap $/B, high power consumption
- R/W: slow (ms), latency, block xfer
- reliability via redundancy (RAID)
SSD (solid state drive)
- medium (500GB), moderate $/B, low power consumption
- R: fast (µs), byte/page xfer; W: mod (100µs), block erase
- reliability: limited block erasures
RAM (random access memory)
- small (10GB), high $/B, low power consumption, volatile
- R/W: fast (ns), byte xfer
